Answer: ST = 4
Step-by-step explanation:
First, make the equation,
9 + 2x + 26 = x + 24
35 + 2x = x + 24 (Combine like terms)
35 + x = 24 (Subtract x from both sides)
x= - 11 (Subtract 35 from both sides)
Plug in to check work,
9 + 2(-11) + 26 = -11 + 24
13 = 13
WAIT, answer the question, it asks for the length of ST.
Plug in the x value for 2x+26,
2(-11)+26 = 4
Thus ST = 4
